TRIP-SCALE PAN.

Specification of Letters Patent.

Patented Feb. 15, 1921.

Application filed March 27, 1920. Serial No. 369,181.

T 0 all whom it may concern Be it known that I, FREDERICK M. STEvnNs, a citizen of the United States, and resident of: New York city, in the county of New York and State of New Yor have invented certain new and useful Improvements in Trip-Scale Pans, of which the following is a mgecilication.

This invention relates to scale plates and has for its object to provide a scale plate of improved strength and cheaper construction than heretofore provided in this art.

As is well understood, these plates are usually flat on top and two are used in a trip scale, one for carrying the scoop and the other for the weights. These plates are subject to heavy usage and are reqliiired to be durable on top and also to be fi 'mly at- According to this invention, tl e upper surface of the plate is composed of sheet metal and is reinforced by an inner plate carrying a tln'cadcd socket or nut. Breakages have hert-ztoiore frequently occurred in this at taching device, or else to prevent such breakages it has been necessary to employ an expensive and heavy construction. By this invention the scale plate is composed of two plates secured together in such form as to give suilicient stillness to hold the neces sary load, and to the lower member a nut is attached. One plate is drawn down to form a pocket in which a nut can be held, the two plates and the nut being permanently sembled as by turning over the edge of the outer plate on the inner plate. Thereby a strong, neat, light and cheap construction is provided which does away with under braces and also with breakage in use where a single thick plate is used. The invention shown ith reference to a preferred form in the accompz'tnying drawing wherein Figure 1 is a section of a scale plate enr bodying the invention, and

Fig. 2 is a bottom plan view.

1 represents the end of the upright lever of a scale of usual construction," having the threaded end 2. 3 represents the upper plate composed of a sheet having a downturned edge 4, which is turned over onto the downturned edge of the lower plate 5, thereby forming a firm and permanent assembly. The upper plate can be finished when made, as subsequent assembling will not mar the finish. Suitable finishes are by turning, japanning, enameling, etc. Before assembl1ng, the lower plate 5 is punched with a plurality of holes, 6, and a central hole 7, and is then drawn down in a press to provide an angular cup or recess 8. In this recess 8 is placed a nut 9 which is permanently held therein against displacement and rotation. by the securing together oi the two plates, 3, 5. I

Before drawing out the cup 8, the holes 6 were originally punched round, preferably one for each side of the nut, but in drawing out and down the holes assume the shape shown in Fig. 2, the central hole.7 being originally punched smaller than appears inFig. 2, but enlarges in the drawing oper ation so as to freely receive the end 2 of the upright 1. T he advantage of first punching the holes is that the metal will readily draw down to the required depth without breaking, whereas without punching the roles, breakage of the metal would be practically certain to happen, in the kind of material used for the purpose.

What is claimed is 1. A scale plate comprising an upper plate, a lowerplate secured thereto and hav ing a depending open ended recess, and a nut in said recess adapted to receive the attaching member of the scale.

2. A scale plate comprising an upper plate, provided with a down turned rim, a lower plate fitting within said flange and having a depending open ended drawn re cess of angular shape to fit a nut, a nut fitting said recess flush with the lower surface or the upper plate to receive the attaching member of the scale, and means securing the nut and said plates together.

3. A scale plate composed of an upper and lower sheet metal member, suitably attached together, and a threaded nut attached to the lower member.

el. A scale plate composed of an upper and lower sheet metal membcnthe members having flanges drawn cup shape, and one fitting inside the other, the outer one having the edge of the flange turned over the edge of the inner one to fasten them together, and a threaded nut attached to the inner side of the lower member.

5. A scale plate composed of two component sheet metal parts, the surface of the upper one covered with a suitable finish before assembling together with a threaded nut attached to the lower part.
